IMPROVEMENT IN METALLIC RIDGE-CAPS FOR ROOFS.

Specification forming part of Letters Patent No. 157,132, dated November24, 1374 application filed May 18, 1874.

To all whom it may concern Be it known that I, PETER B. LAIDLAW, of FortWayne, in the county of Allen and State of Indiana, have inventedcertain new and useful Improvements in Roofing; and I do hereby declarethat the following is a full and exact description thereof, referencebeing had to the accompanying drawings and to the letters of referencemarked thereon, in which like letters refer to like parts in thedili'erent figures.

To enable others skilled in the arts to make and use my invention, Iwill proceed to describe its construction and operation.

The nature of my invention consists in the construction and combinationof certain devices which form a ridge-cap for root's.

In the drawings, A represents the ridge of a building, the roof of whichmay be of slate or other material. B B represent brackets, which aresecured at one end to the ridge of the building by means of screws ornails, as seen in Fig. 1. Said brackets are placed on said ridge at asuitable distance apart, and their adjacent ends are bent upward at aright 0 0 represent rods, which are secured in position, as seen in Fig.1, between said brackets, by which they are supported.

Said rods may be round or in any other desired form, and of any desiredlength or size, and of any suitable distance apart.

D represents a cap, which is formed from sheet metal, as seen in Fig. 2,so as to fit easily over said rod 0. This cap is so formed that its apexis cylindrical, as seen in Fig. 2, or it may assume any other desiredform. E represents a clamp, which is secured, as seen in Fig. 3, on theoutside of said cap, for the purpose of holding the same in the desiredposition.

When the slatin g is completed the brackets B B are placed in positionon the ridge at a proper distance from each other. C are then secured asdescribed. The cap is then passed on over said rods in sections aboutsix feet long. They are so adjusted that their ends overlap each otherand form a joint. When this is done the clamps are adjusted to theirplaces and the work is complete, thus forming a neat and durable finishto the roof without the use of a continuous rod, which is a matter ofgreat importance in practice.

WVhat I claim as new, and desire to secure by Letters Patent, is-

The combination of the brackets B, sectional rods 0, sectional cap D,and clamp E, constructed and arranged as and for the purpose specified.
